Under-exposure

To correct this result it is recommended to change the following parameters in
their order of appearance:
1. increase the Exposure Time
2. increase the Gain
NOTE
In general, a longer exposure time corresponds to a lighter image but is
susceptible to blurring due to code movement. Exposure time is also lim-
ited by the Internal Lighting mode parameter. Longer exposure times can
be set if the power strobe level is lowered.
High gain settings may produce a grainy image that may affect the decod-
ing process.
